PR^ENUNCI/E  BAHAMENSES  — I. 


CONTRIBUTIONS  TO  A  FLORA  OF  THE  BAHAMIAN  ARCHIPELAGO. 


CHARLES  F.  MILLSPAUGH,  M.D. 


During  field  and  herbarium  studies  of  the  flora  of  the  Greater  An¬ 
tillean  Islands,  conducted  by  Dr.  N.  L.  Britton,  Director  of  the  New  York 
Botanical  Garden,  and  the  Author,  each  came  to  the  conclusion  that  a 
thorough  investigation  of  the  Bahamian  Archipelago  would  throw  much 
desired  light  upon  many  problems  of  plant  distribution  and  mutation, 
and  offer  a  probable  solution  of  the  question  of  the  age  of  these  interest¬ 
ing  islands. 

A  joint  investigation  of  such  collections  as  had  been  previously  made 
on  the  archipelago  proved  them  to  be  in  many  cases  meagre  in  material,  scrap¬ 
py  in  character,  or  from  islands  too  widely  separated  to  afford  even  a  par¬ 
tial  solution  of  the  problems  presented.  They  therefore  decided  to  so¬ 
licit  the  consent  of  those  botanists  representing  the  Government  of  Great 
Britain,  to  which  these  islands  belong,  and  the  support  of  the  institutions 
they,  themselves  represent,  in  view  of  organizing  a  thorough  exploration 
of  the  islands  included  in  the  archipelago.  This  being  in  both  instances 
unhesitatingly  given,  three  expeditions  were  equipped  for  immediate  field 
work  and  others  planned,  to  cover  within  the  next  two  years,  all  the  is¬ 
lands  included. 

Up  to  the  present  writing,  the  survey  thus  organized  has  covered  the 
following  groups: — Great  Bahama,  the  Abacos,  the  Isaacs,  the  Berry  Is¬ 
lands,  the  Bimini  Islands,  the  New  Providence  area,  the  Exuma  Chain, 
the  Inaguas  and  Grand  Turk.  In  these,  a  large  amount  of  information 
and  material  has  been  accumulated  by  Dr.  and  Mrs.  Britton,  Mr.  Nash, 
Mr.  Brace,  and  the  Author.  In  accomplishing  this,  not  only  have  the 
usual  lines  of  communication  been  utilized,  but  special  vessels  have  been 
equipped  and  commissioned.

The  following  material  (over  7,000  sheets),  resulting  from  this  survey, 
or  secured  by  exchange,  gift,  loan,  or  purchase,  is  deposited  in  duplicate 
in  both  institutions,  where  it  is  being  studied  by  the  co-workers,  who  are 
also  taking  occasion  at  various  intervals  to  consult  the  collections  of  Cates- 
by,  Eggers,  Hjalmarsson,  Brace,  Daniell,  Herrick,  Allen,  Barbour  &  Bryant, 
and  others,  deposited  in  European  and  American  herbaria.  In  addition, 
a  complete  series  of  the  orchids,  cacti,  tillandsias,  and  other  difficult 
groups  is  being  collected  alive  and  studied  in  the  conservatories  of  the 
Garden. 

COLLECTORS. 

Brace  —  Mr.  Louis  J.  K.  Brace  began  his  collections  in  the  Bahamas  in 
1875.  He  worked  principally  on  New  Providence  until  1880,  but 
also  secured  material  on  Fortune  Island  or  Long  Cay,  and  Andros. 
His  work  resulted  in  about  525  numbers,  which  were  sent  to  Kew  Gar¬ 
dens.  A  duplicate  set  is  still  in  his  possession.  He  began  field  work 
under  the  present  survey  in  September,  1904  (see  Britton  &  Brace), 
and  later  in  the  same  year  was  commissioned  by  the  Garden  to  make 
an  exploration  of  the  Abaco  Islands,  where  he  collected  as  follows: 
Green  Turtle  Cay  (1475-1515),  Allen’s  Cay  (1526-54),  Spanish 
Cay  (1555-62),  Man-o’-War  Cay  (1563-89),  Pigeon  Cay  (1662-73), 
Elbow  Cay  (1688-1712),  and  on  the  island  of  Abaco  at  Butler  Bay 
(1516-25),  Marsh  Harbor  (1590-1661,  1713-53,  1787-1846),  Great 
Cistern  (1674-87,  1754-86),  Cherokee  Sound  (1847-9,  1898-1980, 
1999,  2080-84,  2086),  Eight  Mile  Bay  (1850-97),  opposite  Cherokee 
Settlement  (1981-98,  2064-79),  Old  Kerr’s  Point  (2000-2036),  and 
California  road  (2037-63),  a  total  of  61 1  numbers.  Following  this 
expedition  he  continued  work  on  New  Providence  in  localities  from 
which,  from  time  to  time,  it  became  necessary  to  have  more  material 
of  previously  secured  species. 

In  June,  1905,  a  commission  was  given  him  by  both  the  Garden 
and  this  Museum  to  continue,  on  Great  Bahama,  the  work  already 
undertaken  there.  (See  Britton  &  Millspaugh.)  On  this  exploration 
he  collected  at  Eight  Mile  Rocks  (3633-5,  3671-3738),  Deadman’s 
Reef  (3631-2),  and  the  western  extremity  of  the  island  (3484-3630, 
3636-57).  He  also  collected  Garden  Cay  (3658-70),  and  visited 
(during  his  sailings  to  and  from  Great  Bahama)  North  Bimini 
(3461-75,  3479-83),  South  Bimini  (3476-8),  North  Cat  Cay  (3739- 
54),  and  Andros  Island  (3755-6),  and  after  returning  to  New  Provi¬ 
dence  collected  Nos.  3893-3918. 

Britton  —  Dr.  N.  L.  Britton  collected  on  New  Providence  in  April,  1904, 
in  the  neighborhood  of  Nassau,  South  Side  Beach,  Blue  Hills,  Far-

ringdon  Road,  West  Bay  Street  Road,  Cunningham  Road,  Lake 
Cunningham,  and  Old  Fort.  In  this  preliminary  investigation,  in 
company  with  the  Author  (see  Millsp.),  he  collected  158  numbers, 
(1-158).  An  account  of  the  field  work  is  published  in  the  Journal  of 
the  New  York  Botanical  Garden  5:  129-136. 

See  also  Britton  &  Brace,  and  Britton  &  Millspaugh. 

B.  6°  Br.  —  Britton  &  Brace  —  Dr.  N.  L.  Britton,  Mrs.  E.  G.  Brit¬ 
ton,  and  Mr.  Louis  J.  K.  Brace  collected  together  on  New  Providence 
(Nos.  159-328,  361-872),  and  Hog  Island  (329-360),  in  September 
and  October,  1904.  They  ranged  New  Providence  with  great  thor¬ 
oughness,  penetrating  to  the  coast  region  north,  east,  south,  and  west, 
and  to  the  coppices,  pine  barrens,  and  openings  in  the  neighborhood  of 
Nassau,  Fort  Montague,  Farringdon  Road,  Swingate,  Maidenhead, 
Tea  House,  Race  Course,  Delaport,  Fox  Hills,  Village  Road,  Mt. 
Vernon,  Rifle  Range,  Harold  Road,  Carmichael,  Adelaide,  Southwest 
Landing,  Miller’s,  Blue  Hills,  Soldiers  Road,  Lake  Cunningham, 
Winton,  Old  Fort,  Waterloo,  Clifton,  Mt.  Pleasant,  Fort  Charlotte, 
Gambier,  Killarney,  Bonefish  Pond,  and  Seven  Hills.  The  com¬ 
moner  things  were  not  taken,  the  attempt  being  made  to  secure  only 
such  species  as  were  previously  unfamiliar  or  those  which  had  only 
been  gathered  when  out  of  character.  This  survey  resulted  in  714 
particularly  interesting  plants  embracing  the  series  of  numbers  in¬ 
dicated  above. 

An  account  of  this  expedition  is  published  in  the  Journal  of  the 
New  York  Botanical  Garden  5:  201-209. 

B.  6°  M.  — Britton  &  Millspaugh  —  Drs.  N.  L.  Britton  and  C.  F.  Mills- 
paugh,  accompanied  by  Mr.  M.  A.  Howe,  began  an  exploration  of 
the  Berry  Islands,  Great  Bahama,  and  the  Exuma  Chain,  in  January, 
1905.  A  schooner  was  chartered  and  equipped  at  Nassau,  where, 
after  a  day’s  delay  on  account  of  heavy  weather  (during  which  col¬ 
lecting  was  done  in  the  scrublands  and  coppices  south  of  Nassau 
(2085-2110),  the  expedition  began  at  Rose  Island  (2111-2166),  and 
Hog  Island  (2167-2176).  The  first  island  of  the  Berry  Group  vis¬ 
ited  was  Whale  Cay  (2177-2201),  followed  by  Frozen  Cay  (2202- 
2224),  Little  Harbor  Cay  (2225-2254),  Great  Sturrup  Cay  (2255- 
2285),  Goat  Cay  (2286-2301),  Lignum  Vitae  Cay  (2302-2332),  and 
Great  Harbor  Cay  (2333-2354).  The  exploration  began  on  Great 
Bahamalsland  at  Eight  Mile  Rocks  (2355-2596),  and  was  continued  at 
Barnett’s  Point  (2597-2716),  and  Golden  Grove  (2717-2741).  Re¬ 
turning  to  Nassau,  a  fresh  start  was  made  to  the  Exuma  Chain,  of 
which  the  following  islands  were  diligently  searched:  Ship  Channel

Cay  (2742-2767),  Cay  north  of  Wide  Opening  (2768-2804),  Cave 
Cay  (2805-2836),  Little  Galiot  (2837-2850),  Great  Galiot  (2851- 
2860),  Great  Guana  (2861-2922),  Great  Exuma  (2923-3051,  307 3- 
3141),  and  Stocking  Island  (3052-3072). 

On  Great  Exuma  the  regions  worked  were  the  scrub  lands  and 
coppices  lying  west  of  Georgetown;  Hayne’s  Road  from  the  east  to 
the  west  shores  across  the  island;  and  the  Rolletown  scrub  lands  and 
coppices.  The  total  series  of  this  exploration  is  1057  sheets. 

An  account  of  this  expedition  may  be  found  in  the  Journal  of 
the  New  York  Botanical  Garden  6:  77-85. 

Coke?-  —  Dr.  William  C.  Coker,  botanist  of  the  Bahamian  expedition  of 
the  Geographical  Society  of  Baltimore,  assisted  by  Messrs.  C.  A. 
Shore  and  F.  M.  Hanes,  collected  in  the  summer  of  1903  on  the  fol¬ 
lowing  islands:  New  Providence  (1-193,  247-305,  551),  Andros  Is¬ 
land  and  Little  and  Great  Mangrove  Cays  (194-234),  Green  Cay 
(235-246),  George’s  Island  (306-317),  Eleuthera  (318-421),  Cat  Is¬ 
land  (422-437),  Rum  Cay  (438-457),  Watlings  Island  (458-491, 
521,  528),  Long  Island  (492-520,  524),  Water  Cay  (523,  525),  Abaco 
(558-568,  575-6),  and  Elbow  Cay  (569-574).  This  collection  was 
deposited  in  the  herbarium  of  the  New  York  Botanical  Garden,  and 
forms  the  basis  of  his  “Vegetation  of  the  Bahama  Islands,”  in  Shat- 
tuck’s  “The  Bahama  Islands.”  Owing  to  the  insufficiency  of  the 
material  secured  many  phanerogams  therein  published  are  based 
upon  provisional  determination  only.  The  cryptogams  exist  under  a 
separate  series  of  numbers. 

Coope ?- —  Dr.  William  Cooper  paid  a  visit  to  New  Providence  in  1859  for 
the  purpose  of  making  dredgings  for  zoological  material.  While 
there  he  collected  in  the  neighborhood  of  Nassau  about  100  plants  for 
his  friend,  Dr.  John  Torrey.  The  prime  set  of  these  plants  is  now 
in  the  herbarium  of  the  New  York  Botanical  Garden.  See  Bull.  Tor¬ 
rey  Club  1  7  : 190. 

Curtiss — Mr.  A.  H.  Curtiss  collected  his  first  series  of  “West  Indian 
Plants”  in  April,  1903,  in  the  neighborhood  of  Nassau,  New  Provi¬ 
dence.  This  series  comprises  numbers  1-211,  of  which  the  prime 
set,  with  the  unnumbered  unicates,  is  deposited  in  the  herbarium  of 
the  New  York  Botanical  Garden,  and  the  first  distributed  set  in  the 
herbarium  of  this  Museum. 

Earle —  Prof.  F.  S.  Earle  collected  during  one  day  only,  on  New  Provi¬ 
dence  (Nos.  1-79),  while  on  his  way  to  Cuba,  in  March,  1903.  His 
plants,  largely  from  the  vicinity  of  Nassau,  are  in  the  herbarium  of 
the  Garden.

E.  G.  B.  —  Mrs.  N.  L.  Britton,  often  accompanied  by  Mr.  Brace,  visited, 
in  April  and  May,  1905,  all  those  stations  on  New  Providence  pre¬ 
viously  collected  by  Britton  &  Brace,  at  which  it  had  become  desir¬ 
able  to  secure  additional  material  of  interesting  plants  or  characters 
missing  on  previous  notable  species.  In  addition  to  achieving 
marked  success  in  this  undertaking,  she  secured  many  other  plants 
of  particular  interest.  Her  survey  resulted  in  310  sheets  (Nos. 
3141-3460),  and  is  mentioned  in  the  Journal  of  the  -New  York  Bo¬ 
tanical  Garden  5:129-136.  See  also  Britton  &  Brace. 

Hitchcock  —  Dr.  J.  T.  Rothrock  and  Prof.  Albert  S.  Hitchcock  collected 
in  the  Bahamas  in  November  and  December,  1890.  The  collections 
were  largely  made  by  Prof.  Hitchcock  on  New  Providence,  Eleuthera, 
Cat,  Watlings,  Crooked,  Fortune,  and  Inagua,  and  form  the  basis 
of  his  “Plants  collected  in  the  Bahamas,”  etc.  The  material  collect¬ 
ed  was  deposited  in  the  herbarium  of  the  Missouri  Botanical  Gar¬ 
den,  from  which,  through  the  kindness  of  the  director,  Dr.  William 
Trelease,  the  author  has  been  allowed  to  reassemble  the  sheets.  The 
collection,  embracing  about  600  sheets,  is  at  this  writing  a  loan  to 
the  Field  Columbian  Museum. 

Howe — Dr.  Marshall  A.  Howe,  algologist  of  the  New  York  Botanical 
Garden,  has  collected  extensively  the  sea  vegetation  of  the  Bahamas, 
accompanying  Dr.  Britton  and  the  author  on  their  first  trip,  and 
later,  Britton  &  Millspaugh.  He  also  accompanied  the  author  up¬ 
on  the  Bimini  explorations.  See  Journal  New  York  Botanical  Gar¬ 
den  5:129-1-36  and  6:77-85. 

Millsp.  —  C.  F.  Millspaugh — the  author  began  his  collections  among 
the  islands  on  New  Providence,  in  April,  1904,  in  company  with  Dr. 
Britton  (see  Britton),  visiting  substantially  the  same  stations,  where, 
as  his  collecting  was  to  extend  to  other  islands,  each  kept  his  indi¬ 
vidual  series  of  numerals.  He  collected  at  the  following  localities: 
Blue  Hills  (2048-2100),  South  Shore  (2101-2151  and  2262-2277), 
West  Bay  Street  road  (2152-2178),  pine  barrens  and  hammock  lands 
along  Lake  Cunningham  road  (2179-2217),  region  of  Lake  Cun¬ 
ningham  (2218-2244),  Farringdon  Road  (2245-7),  Swingate  (2248- 
51),  Old  Fort  (2252-4),  and  Waterloo  (2255-61).  Then  hiring  and 
commissioning  a  sloop,  he  sailed  in  company  with  Dr.  M.A.  Howe(see 
Howe)  for  an  investigation  of  the  Bimini  Islands,  collecting  at  the 
following  stations:  West  End  Bight,  New  Providence  (2278-2293), 
Joulter’s  Cays  (2294-2304),  Gun  Cay  (2305-2328),  North  Cat  Cay 
(2329-2347,  2415),  South  Bimini  (2348-236 8,  2379-85,  2387-98,

2406-2414),  North  Bimini  (2369-78,  2386,  2399-2405),  South  Cat 
Cay,  (2416-2441).*  Again  in  January,  1905,  he  collected  in  the  fol¬ 
lowing  localities  while  awaiting  the  arrival  of  Dr.  Britton  (see  Brit¬ 
ton  &  Millspaugh):  Blue  Hills  road  (2442-4,  2461-81),  Silver  Cay 
(2445-2460),  and  South  Side,  Soldiers  Road,  Fort  Montague  and 
Fort  Fincastle  (2482-2502).  Following  immediately  upon  this,  see 
Britton  &  Millspaugh. 

\ 

N.  6°  T.  —  Nash  &  Taylor — Messrs.  Geo.  V.  Nash  and  Norman  Taylor, 
of  the  New  York  Botanical  Garden,  were  commissioned  by  the  Gar¬ 
den,  in  October,  1904,  to  investigate  the  Inaguas.  They  made  an 
exhaustive  survey  of  the  islands,  collecting  on  Inagua  482  numbers 
(874-1138  and  1258-1474),  on  Sheep  Cay  23  numbers  (1 139-1161), 
and  on  Little  Inagua  96  numbers  (1162-1257).  In  September,  1905, 
on  their  return  from  an  exploration  in  Haiti,  they  spent  a  week  on 
Grand  Turk  Island,  collecting  all  such  plants  as  were  noted  by  them 
at  that  season,  136  numbers  (3757-3892.)  Accounts  of  these  expe¬ 
ditions  may  be  found  in  the  Journal  of  the  New  York  Botanical  Gar¬ 
den  6:1-19  and  189-191. 

Northrop — Mrs.  Alice  (Rich)  Northrop,  accompanied  by  her  husband, 
Prof.  John  I.  Northrop,  made,  in  1890,  a  large  collection  of  the 
plants  of  New  Providence  (Nos.  1-239,  280-331),  Rose  Island  (251), 
Salt  Cay  (240-244,  271-279),  Hog  Island  (245-8,  252-70),  and  An¬ 
dros  (332-758).  These  plants  formed  the  basis  of  Mrs.  Northrop’s 
“Flora  of  New  Providence  and  Andros.”  They  are  now  deposited 

in  equal  sets  in  the  herbaria  of  this  Museum  and  the  Garden. 

/ 

Wight  —  Mr.  Alex.  E.  Wight,  under  the  patronage  of  the  Gray  Herbari¬ 
um,  of  Cambridge,  Mass.,  made  a  Bahamian  collection  of  275  num¬ 
bers  from  March  to  May,  1905.  He  collected  on  New  Providence 
and  Hog  Island  (Nos.  1  226  and  271-275),  and  on  Andros  (227- 
270).  The  resulting  plants  are  being  determined  at  the  Gray  Her¬ 
barium,  where  the  initial  set  will  be  retained  and  the  duplicate  sets 
distributed  to  this  Museum,  the  New  York  Botanical  Garden,  and 
others.  Prof.  B.  L.  Robinson  has  kindly  communicated,  in  advance, 
to  the  author  all  those  numbers  falling  within  the  natural  orders 
treated  in  this  Praenuncia.

Croton  cascarilla  (L).  Linn. 

This  species,  first  depicted  by  Catesby  vol.  2  plate  46,  has  only  been 
collected  once  since,  then  on  New  Providence  by  Mr.  W.  F.  Daniell, 
whose  specimen,  as  seen  by  Dr.  Britton,  proves  Catesby’s  drawing  to  be 
a  good  representation  of  the  species.  All  other  reports  of  the  species 
from  the  Bahamas  or  Antillean  Islands  are  in  error  and  are  principally 
based  upon  forms  of  Croton  linearis.  Prof.  Hitchcock’s  specimens  are 
not  this  species. 

Croton  discolor  Willd.

*Dr.  Britton  finds  that  Wright’s  type  of  Croton  homolepidus  in  herb.  British  Museum  is  the  same 
as  B.  &  M.  2339,  and  identical  with  Catesby’s  specimen  of  C.  eluteria.

E.  buxifolia  flexuosa  (Kth.)  Boiss.  Anyone  seeing  this  species  in  the

Its  purplish  coloration,  cinereous  glaucescence,  rounded  flat  leaves 
and  spreading  habit  cause  it  to  resemble  E.  Cayensis  far  more  closely 
than  E.  buxifolia. 

Leaves  glauco-cinereous,  ovate,  rounded  at  the  apex  and  unequal 
base  .3-1  cm.  x  .2— .6  cm.  Involucres  turbinate,  short  pediceled,  smooth

representing  the  extremes  of  this  species  are  so  widely  different  in  gen¬ 
eral  appearance  as  to  almost  convince  one  that  they  represent  two 
strongly  .marked  species.  This  difference,  however,  lies  entirely  in  the 
habit  of  the  plants  and  the  size  of  the  leaves.  The  tallest  erect  form 
with  small,  ovate  leaves  (3796)  passes  through  the  type  (3888)  to  a 
more  diffuse,  larger  leaved  form  (1305)  and  a  fully  prostrate  plant  with

less  intumescent  margin.

2  -  4.  5  cm.  wide,  varying  from  acute  to  obtuse  at  the  apex,  narrowed 
at  the  base,  coriaceous,  dark  green  and  shining  above,  paler  and  dull 
beneath,  the  midvein  impressed  on  the  under  side,  the  lateral  veins  few 
and  obscure,  the  petiole  slender,  2-3  mm.  long  ;  racemes  few-flowered, 
shorter  than  the  leaves  or  about  equalling  them  ;  pedicels  about  as  long 
as  the  calyx,  or  sometimes  a  little  longer  ;  calyx  campahulate  2  mm. 
long  ;  corolla  funnel-form-campanulate,  about  5  mm.  long,  white  or 
cream  color,  veined  with  purple  ;  berry  white,  somewhat  compressed, 
4  —  6  mm.  in  diameter. 

Differs  from  C.  parvifolia  Wullsch.  by  its  smaller  darker  green 
leaves,  smaller  pale  corolla  and  less  compressed  berries.  C.  pinetorum 
occurs  only,  so  far  as  known,  on  islands  inhabited  by  Pinus  bahamensis

Valentine  Nash,  who,  in  his  energetic  field  work  in  the  Bahamas,  South 
Florida  and  Haiti,  has  rediscovered  many  little  known  species  and 
amassed  very  valuable  collections  toward  a  flora  of  these  regions.

Cat  Island  — -  Hitchcock. 

Mr.  Hitchcock’s  plant,  while  having  (on  account  of  its  greatly  re¬ 
duced  leaves)  a  quite  distinct  general  appearance  of  difference  from  C. 
fulva  (as  well  represented  by  C.  Wright’s  1357  Monte  Verde,  Cuba, 
May  30,  1859,)  nevertheless  has  no  other  characters  of  differentiation. 
It  is  fairly  well  connected  in  leaf  size  and  form  with  the  Wright  plant 
through  Mr.  Wright’s  other  1357  collected  at  the  base  of  Farallonesr 
Sept.  29,  i860,  which  is  in  the  same  fruiting  stage  as  the  Hitchcock 
plant.  Of  this  Farallones  plant  Mr.  Wright  says,  “  A  slender  bush  6 
to  10  feet  high:  in  thick  woods.” 

Sauvalle  (FI.  Cub.  113)  considers  this  species  synonymous  with  the 
Jamaican  C.  ferruginea  Swartz,  this  however  is  not  the  case,  the  differ¬ 
ences  are  broad  and  evident.

The  specimens  agree  with  those  of  Combs,  Calicita,  Cuba  239,  and 
Shafer,  Madruga,  Cuba  74.  There  are  two  plants  of  Wright,  Cuba  ori- 
entali  bearing  his  number  421,  one  being  this  species  and  the  other  P. 
ilicifolium,  evidently  a  case  of  attempted  matching  of  plants  before 
distribution,  unfortunately  therefore  I  am  compelled  to  take  the  later 
gathered  Bahamian  plant  for  the  type. 

The  foliage  form  and  shape  is  very  variable,  never  however  even  ap¬ 
proaching  that  of  P.  ilicifolium,  in  which  the  margins  are  crenate  and 
spinous  throughout,  while  those  of  P.  Wrightii  are  simply  spinous  and 
that  only  on  the  upper  half  of  the  leaf.  Both  sides  of  the  leaf  in  P. 
ilicifolium  are  pubescent,  while  in  P.  Wrightii  the  upper  side  is  shin¬ 
ing  and  strongly  reticulate,  while  the  lower  surface  is  resinous  pulver¬ 
ulent.

STUDIES 


BY  J.  M.  GREENMAN. 


The  present  paper  embodies  the  results  of  a  study  of  the  material 
representing  the  genus  Citharexylum  in  the  collections  of  John 
Donnell  Smith,  the  Gray  Herbarium,  and  the  herbarium  of  the  Field 
Museum  of  Natural  History.  It  is  intended  as  preliminary  to  a 
synoptical  revision  of  the  group,  which  the  writer  already  has  well 
under  way.  The  generic  limitations  are  those  of  Bentham  &  Hooker,  f. 
Genera  Plantarum,  ii,  1149,  and  of  Briquet  in  Engler  &  Prantl,  Die 
natiirlichen  Pflanzenfamilien,  iv.  Ab.  3a,  159;  and  the  Latin  form  of 
the  generic  name  is  that  adopted  by  Linnaeus  in  the  first  edition  of 
the  Species  Plantarum,  notwithstanding  the  earlier  use  of  the  Greek 
termination.  The  writer  desires  to  express  his  thanks  to  Mr.  John 
Donnell  Smith  for  the  loan  of  his  excellent  suite  of  specimens  of  this 
genus,  and  to  Prof.  B.  L.  Robinson  of  the  Gray  Herbarium,  where  the 
greater  part  of  this  work  was  done. 

Citharexylum  Bourgeauianum,  sp.  nov.

ing  the  stem  and  branches  in  elongated  racemes,  occasionally  some¬ 
what  paniculately  disposed,  2  dm.  or  less  in  length,  hirsutish  pubescent; 
bracts  subulate,  1  to  2  mm.  long,  equaling  or  slightly  exceeding  the 
stoutish  pedicels,  soon  recurved  and  more  or  less  persistent:  calyx 
somewhat  tubular  or  deeply  cup-shaped,  about  5  mm.  long,  crenately 
5-lobed,  hirtellous  on  the  outer  surface  and  slightly  puberulent  within: 
corolla  subsalverform,  while;  tube  equaling’  or  barely  exceed¬ 
ing  the  calyx,  pubescent  in  the  throat;  lobes  oblong,  3  mm.  long, 
pubescent  011  both  surfaces:  fruit  not  seen.  —  Mexico.  State  of  Vera

tic-oblong  to  subobovate,  including  the  petiole  1  to  2  cm.  long,  5  to  12 
mm.  broad,  usually  short  acuminate  or  somewhat  pungent-tipped, 
entire  or  occasionally  bearing  1  or  2  teeth  on  either  margin,  glabrous 
on  both  surfaces,  conspicuously  impressed-punctate  above,  minutely 
punctate  under  a  lens  beneath,  narrowed  at  the  base  into  a  short

which,  however,  it  differs  in  having  smaller  and  entirely  glabrous 
leaves  with  an  entire,  not  spinose-dentate,  margin.  The  striking 
impressed  punctation  of  the  leaves  of  C.  punctatum  serves  as  an 
excellent  diagnostic  character.

New  or  Noteworthy  Spermatophytes  from  Mexico, 
Central  America,  and  the  West  Indies. 

By  J.  M.  GREENMAN. 


The  diagnoses  and  notes  here  presented  are  the  results  of  critical 
study  in  the  determination  of  several  recent  collections  of  plants 
from  Mexico,  Central  America  and  the  West  Indies,  particularly 
those  of  Mr.  Edward  A.  Goldman,  Professor  Cassiano  Conzatti,  Dr. 
George  F.  Gaumer,  Professors  C.  R.  Barnes,  C.  J.  Chamberlain  and 
W.  J.  G.  Land,  Dr.  Charles  F.  Millspaugh,  Dr.  J.  N.  Rose  and  assist¬ 
ants,  Sr.  Dr.  Fernando  Altamirano,  Professor  W.  A.  Kellerman, 
the  late  Dr.  G.  M.  Emrick,  Mr.  H.  A.  Van  Hermann,  and  several 
others  including  the  writer.  The  material  of  certain  groups,  especially 
in  the  genus  Senecio  collected  by  Mr.  C.  G.  Pringle,  has  been  gener¬ 
ously  submitted  to  me  for  identification  by  Professor  B.  L.  Robinson. 
The  new  species  here  proposed  in  this  genus  are  preliminary  to  a 
forthcoming  monograph  of  the  North  American  Senecios. 

Cyperus  ochraceus  Vahl,  Enum.  ii.  325  (1805). 

Specimens  agreeing  well  with  the  original  description  and  with 
West  Indian  representatives  of  this  species  were  collected  at 
Laguna,  near  the  City  of  Vera  Cruz,  Mexico,  22  January,  1906, 
J.  M.  Greenman ,  no.  30  (hb.  Field  Mus.).  -This  species  seems 
not  to  have  been  noted  by  Hemsley  in  the  Biologia  Centrali- 
Americana. 

Hechtia  macrophylla  Greenman,  sp.  nov. 

Leaves  about  1  m.  in  length,  3.5  cm.  broad  just  above  the  base, 
gradually  tapering  to  the  apex,  glabrous  above,  lepidote-cinere- 
ous  beneath;  margins  spinose;  spines  3  cm.  or  less  apart,  up¬ 
wardly  curved,  6  mm.  or  less  in  length,  usually  bearing  a  tuft  of 
persistent  white  floccose  tomentum  in  the  axils:  inflorescence 
paniculate,  about  4  dm.  long,  1.5  to  2  dm.  broad,  lepidote- 
tomentulose;  ultimate  branches  2  to  12  cm.  long,  spicate,  more 
or  less  loosely  but  evenly  flowered  throughout  their  entire  length ; 
floral  bracts  ovate,  acute,  4  mm.  long:  staminate  flowers  sessile, 
about  5  mm.  long  in  anthesis,  spreading  or  reflexed;  sepals

248  Field  Columbian  Museum  —  Botany,  Vol.  II. 

broadly  ovate,  2.5  mm.  long,  acute;  petals  elliptic  or  elliptic- 
obovate,  about  4  mm.  long,  strongly  concave,  free  or  slightly 
united  at  the  base;  ovary  rudimentary:  pistillate  flowers  and 
fruit  unknown. —  Mexico.  State  of  Vera  Cruz:  Carrizal,  12  to 
14  May,  1901,  E.  A.  Goldman ,  no.  712  (hb.  U.  S.  Nat.  Mus.; 
fragment  and  photograph  in  hb.  Field  Mus.). 

The  species  here  described  is  apparently  nearest  related  to 
Hechtia  Schottii  Baker,  and  H.  texensis  Watson;  from  the  for¬ 
mer  it  differs  in  having  longer  leaves,  more  profusely  branched 
inflorescence,  and  somewhat  smaller  floral  bracts;  from  the 
latter  it  is  readily  separated  by  the  longer  leaves,  the  presence 
of  conspicuous  tufts  of  tomentum  in  the  upper  axils  of  the 
leaf-spines,  and  by  the  smaller  and  more  scattered  flowers. 

Hechtia  Schottii  Baker,  in  Hemsl.  Biol.  Cent. -Am.  Bot.  iii.

Phan.  ix.  548  (1896). 

In  the  herbarium  of  the  Field  Museum  there  is  a  specimen, 
collected  by  Schott  in  Yucatan,  which  is  unmistakably  refer¬ 
able  to  Hechtia.  The  label  accompanying  the  plant  bears  no 
number,  and  likewise  no  time  of  collection,  but  it  bears  the 
data  “Maxeana.”  The  specimen  consists  of  leaves,  an  inflores¬ 
cence  of  staminate  flowers,  and  a  portion  of  a  panicle  bearing 
mature  fruit.  The  characters  exhibited  by  all  these  parts 
agree  well  with  Baker’s  description,  hence  the  plant  is  confi¬ 
dently  referred  to  the  above  species;  and,  moreover,  it  probably 
represents  a  part  of  the  same  collection  on  which  the  species  was 
founded.  With  this  species  are  also  identified  specimens  collect¬ 
ed  at  Xcholac,  Yucatan,  Dr.  Geo.  F.  Gaumer,  no.  578  (hb. 
Field  Mus.).

Fruiting  specimens  of  this  species  were  collected  by  the  writer 
at  Izamal,  Yucatan,  in  February  of  1906.  These  agree  in  habit 
and  foliar  characters  with  flowering  specimens  which  were 
secured  in  the  same  locality  by  Dr.  A.  Schott  and  also  by  Dr. 
Geo.  F.  Gaumer.  The  species  is  widely  distributed,  occurring 
from  Mexico  to  South  America,  and  although  well  known  from 
flowering  specimens,  the  fruit  seems  not  to  have  been  hitherto 
described,  hence  the  following  characterization  is  here  given: 


Dec.  1907.  Spermatophytes  from  Mexico  —  Greenman.  249 

Mature  capsules  large,  3.5  to  4  cm.  long,  subcylindrical  or  obtusely 
triangular,  short-acuminate  at  the  apex;  valves  dorsally  pale- 
stramineous,  glabrous,  1 -nerved,  recurved  and  somewhat 
spirally  twisted ;  exocarp  readily  separating  from  the  endocarp ; 
seeds  including  the  coma  about  3  cm.  long. —  Mexico.  State 
of  Yucatan:  Izamal,  21  February,  1906,  ].  M.  Greenman ,  no. 
404  (hb.  Field  Mus.). 

Tradescantia  floridana  Watson,  Proc.  Am.  Acad.  xvii.  381  (1882). 
Tradescantella  floridana  Small,  FI.  Southeastern  U.  S.  238 
(I9°3)- 

Dr.  Sereno  Watson  very  clearly  defined  the  above  species 
and  pointed  out  the  characters  by  which  it  is  readily  distinguished 
from  T.  gracilis  HBK.  to  which  it  was  referred  by  C.  B.  Clarke 
in  DC.  Monogr.  Phaner.  iii.  297  (1881).  The  examination  of 
a  considerable  number  of  specimens  from  Florida  and  elsewhere 
shows  that  Dr.  Watson’s  species  retains  the  distinctive  characters 
originally  ascribed  to  it  without  any  evidence,  at  least  as  far 
as  yet  observed  by  the  writer,  of  intergradation  with  the  South 
American  species.  It  seems  best  therefore  to  regard  T.  flori¬ 
dana  Watson  as  well  worthy  of  specific  rank.  The  following 
specimens  are  identical  in  every  detail  with  Dr.  Watson’s  species. — 
Mexico.  State  of  Yucatan:  Izamal,  Dr.  Geo.  F.  Gaumer,  no. 
573  (hb.  Field  Mus.);  Chichankanab,  Dr.  Geo.  F.  Gaumer ,  no. 
1855  (hb.  Field  Mus.).  This  species  has  not  been  recorded 
hitherto  from  Yucatan. 

Smilax  mollis  Humb.  &  Bonpl.  in  Willd.  Sp.  PI.  iv.  785  (1805); 
A.  DC.  in  DC.  Monogr.  Phaner.  i.  67  (1878);  Hemsl.  Biol.  Cent.- 
Am.  Bot.  iii.  365  (1884). 

Mature  fruiting  specimens  of  this  species  were  collected  on 
old  sand  dunes  along  the  shore,  north  of  the  City  of  Vera  Cruz, 
24  January,  1906,  J.  M.  Greenman ,  no.  116  (hb.  Field  Mus., 
and  hb.  Kew).  The  mature  fruit  in  the  fresh  state  is  bright 
red. 

I  am  indebted  to  Lieut. -Col.  David  Prain,  Director  of  the 
Royal  Botanic  Gardens,  Kew,  for  the  identification  of  this 
plant. 

Pouzolzia  Pringlei  Greenm.  Proc.  Am.  Acad,  xxxiii.  476  (1898). 

This  species,  hitherto  known  only  by  Mr.  Pringle’s  no.  6736 
from  Tomellin  Canyon,  has  been  recollected  at  El  Parion,  Dis¬ 
trict  of  Etla,  Oaxaca,  Mexico,  altitude  1,400  m.,  2  September, 
1906,  C.  Conzatti  no.  1551  (hb.  Field  Mus.).  While  Senor  Con- 
zatti’s  specimens  present  no  additional  characters,  yet  the  collec¬ 
tion  records  a  second  station  towards  mapping  the  distribution 
of  the  species.

Phoradendron  vernicosum  Greenman,  sp.  nov. 

Glabrous  throughout:  younger  parts  more  or  less  vernicose: 
stems  and  branches  terete;  ultimate  branchlets  compressed 
at  the  nodes:  leaves  lanceolate-oblong  to  ovate-elliptic,  often 
slightly  oblique  or  subfalcate,  2  to  7  cm.  long,  1  to  2.7  cm.  broad, 
obtuse  or  rounded  at  the  apex,  entire,  narrowed  below  to  a 
subpetiolate  base,  3-5-nerved:  spikes  sessile  or  essentially  so, 
1  to  3  (rarely  5)  in  the  leaf-axils,  1  to  2  cm.  long;  segments  2  to 
5  (usually  4),  5  mm.  or  less  in  length,  6-12-flowered  in  the 
staminate  spike,  2-flowered  in  the  pistillate  spike;  perianth 
3-merous:  berry  ovate-oblong,  about  5  mm.  long,  not  con¬ 
tracted  below  the  calyx-limb,  more  or  less  glaucous;  endocarp 
distinct,  ovate-oblong,  4  mm.  long,  2  mm.  wide,  abruptly 
acuminate. —  P.  flavescens,  Millsp.  Field  Col.  Mus.  Bot.  Ser.

(hb.  Field  Mus.);  Chichankanab,  Dr.  Geo.  F.  Gaumer ,  nos.  1850, 
2011  (hb.  Field  Mus.). 

The  vernicose  character  of  the  young  stem  and  leaves,  the 
short  axillary  inflorescences,  the  two-flowered  segments  of  the 
fertile  spike  and  the  distinctly  acuminate  endocarp  well  char¬ 
acterize  this  species.  The  nearest  affinity  of  P.  vernicosum  is 
with  P.  Wattii  Krug  &  Urban,  from  which  it  differs  in  having 
relatively  shorter  and  broader  leaves,  the  fruit  not  constricted 
below  the  limb  of  the  calyx,  and  a  smaller  and  distinctly  acu¬ 
minate  instead  of  acute  endocarp.

proposed  resembles  G.  dolichopoda  Donn.  Sm.,  but  it  differs  in 
the  less  acuminate  and  blunt  leaves,  character  of  the  pubescence, 
subrotund  sepals,  larger  petals,  shorter  peduncles  and  stipes. 

G.  Gaumeri  is  rich  throughout  all  its  parts  in  oil-glands,  and 
when  crushed  it  produces  a  pleasant  aromatic  odor.  Dr.  Gaumer 
in  whose  honor  the  species  is  named  states  that  the  plant  is  known 
about  Izamal  under  the  name  of  “  Elemuy,”  and  that  from  it 
is  obtained  one  of  the  most  valuable  medicines  used  in  Yucatan.

having  a  pubescent  inflorescence,  more  oblong  and  copiously 
glandular  petals,  in  having  also  the  inner  or  upper  petal  less

mucronate-acute,  entire,  subtruncate  to  obtuse  at  the  base, 
dark  green  and  substrigose-hirsute  above,  slightly  paler  and 
hirtellous-puberulent  beneath,  more  or  less  glabrate,  3-nerved 
and  bearing  tufts  of  white  villous  hairs  in  the  axils  of  the  veins 
on  the  under  side;  petiolules  stoutish,  about  5  mm.  long,  densely 
tawny-hirsute  above;  stipels  subfalcate-linear,  3  to  4  mm.  long, 
glabrous  or  essentially  so:  inflorescence  in  elongated  axillary 
racemes,  2.5  dm.  or  less  in  length;  rhachis  pubescent;  bracts 
lance-attenuate,  about  7  mm.  long,  pubescent;  pedicels  becom¬ 
ing  12  mm.  in  length,  glabrous  or  nearly  so,  and  as  well  as  the 
bracts  persistent;  bracteoles  subtending  the  calyx,  linear- 
lanceolate  to  lance-oblong,  6  to  7  mm.  long,  1  to  1.5  mm.  broad,

berlain  &  W.  J.  G.  Land,  no.  20  (hb.  Field  Mus.,  and  hb.  Uni¬ 
versity  of  Chicago).  The  species  is  rather  striking  on  account 
of  the  large  membranous  leaflets,  many-flowered  inflorescences, 
persistent  pedicels,  and  the  narrow  bracts  and  bracteoles.  It 
suggests  P.  multiflorus  Willd.  and  P.  pedicellatus  Benth,  but  is 
quite  distinct  from  either  of  them.

Acalypha  mollis  HBK.  to  which  species  some  of  the  specimens 
above  cited  have  been  hitherto  referred  is  described  as  an  herba¬ 
ceous  plant  with  distinctly  pedunculate  spikes,  and  with  2-3- 
flowered  reniform-ovate-n-15-dentate  bracts.  On  these  charac¬ 
ters  alone  A.  Seleriana  may  be  readily  separated.  The  species 
here  proposed  seems  to  be  quite  unique  on  account  of  the  shrubby 
habit,  the  numerous  sender  sessile  or  subsessile  spikes  of  stami- 
nate  flowers,  and  the  pistillate  flowers  solitary  in  the  axils  of 
exceedingly  minute  3-parted  bracts.

rounded  to  acuminate  at  the  apex,  mucronate-acute,  subentire 
or  somewhat  dentate  in  the  lower  half,  obtuse  to  subcordate  at 
the  base,  usually  bearing  on  the  upper  side  at  the  junction  of 
petiole  and  blade  two  subulate  appendages,  pubescent  on  both 
surfaces,  glabrate  above;  petioles  0.5-2. 5  cm.  long,  pubescent; 
stipules  narrowly  lanceolate  to  almost  subulate,  2-6  mm.  long: 
peduncles  1-3  cm.  long,  striate,  pubescent;  the  petaloid  involucral

Some  of  the  specimens  above  cited  have  been  hitherto  doubt¬ 
fully  referred  to  Dalechampia  denticulata  Wright  of  the  West 
Indies.  From  this  species,  however,  D.  Schottii  differs  in  having 
uniformly  smaller  leaves,  shorter  petioles,  smaller  floral  bracts  and 
a  nondilated  stigma.  Moreover,  in  D.  denticulata  the  leaves 
and  floral  bracts  are  distinctly  cordate,  while  in  D.  Schottii 
the  leaves  are  from  obtuse  to  subcordate  at  the  base  and  the 
floral  bracts  are  narrowed  below  to  an  obtuse  base.  The  variety 
trijoliolata  suggests  D.  triphylla ,  var.  mexicana  Mull.  Arg.,  but 
the  latter  has  petioles  very  much  longer  in  proportion  to  the 
length  of  the  leaf-blade.

larger  leaves  which  are  abruptly  caudate-acuminate  and  termi¬ 
nated  by  a  very  slender  acumen,  shorter  peduncles,  essentially 
glabrous  inflorescence,  deltoid  bracts,  sessile  flowers,  and  8 
instead  of  10  stamens. 

The  plant  grows  as  a  rather  profusely  branching  tree  with 
thick  and  somewhat  fleshy  branches  and  twigs.  The  almost 
leafless  condition  of  the  tree  and  its  light  gray  appearance  render 
it  a  conspicuous  feature  of  the  “scrub”  and  woodlands  about 
the  City  of  Izamal.  It  passes  under  the  Mayan  name  of  “Pom- 
olche;”  and  its  stems  are  said  to  be  used  by  the  native  people  in 
making  the  so-called  “Chul”  or  whistles. 

Gouania  Conzattii  Greenman,  sp.  nov. 

Stem  terete  or  slightly  angulate  above,  sparingly  pubescent; 
leaves  alternate,  petiolate,  ovate  or  subrotund-ovate,  rounded  to 
short-acuminate  and  submucronate-acute  at  the  apex,  crenate- 
dentate,  shallowly  cordate  at  the  base,  dark  green  and  hirsute- 
pubescent  above  in  the  younger  stages,  more  or  less  glabrate, 
subtomentose  beneath;  midrib  and  veins  prominent  on  the  under 
side  of  the  leaf;  petioles  1  cm.  or  less  in  length:  inflorescence 
terminating  the  stem  and  upper  branches  in  spicate  racemes 
together  forming  a  more  or  less  leafy  panicle:  flowers  sessile, 
or  on  very  short  pedicels:  calyx-limb  5-lobed;  lobes  triangular- 
ovate,  acute,  entire,  externally  as  well  as  the  entire  inflorescence 
tawny-pubescent;  disk  distinctly  5-lobed  and  the  lobes  about 
one-half  as  long  as  the  lobes  of  the  calyx,  2-dentate  and  more 
or  less  persistent:  petals  strongly  cucullate,  1  mm.  long:  mature 
capsules  triangular,  6  to  7  mm.  high,  including  the  strongly 
developed  wings  7  to  9  mm.  in  diameter,  glabrous  or  nearly  so; 
seeds  oval,  3  to  4  mm.  long,  smooth  and  shining,  convex  on  the 
outer  surface,  2-faced  and  more  or  less  2-scalloped  on  the  inner

tomentosa  Jacq.,  but  differs  in  having  a  sparingly  pubescent 
stem,  larger  flowers,  and  also  in  bearing  capsules  which  are 
nearly  twice  as  long  in  the  vertical  axis,  and  producing  seeds 
which  are  fully  twice  larger  than  G.  tomentosa.

It  is  with  some  hesitation  that  the  writer  describes  a  leafless 
plant  as  new  to  science,  but  the  present  one  is  so  distinctive 
in  its  ligneous  stem,  inflorescence  and  floral  characters  that  it 
seems  best  to  present  the  above  characterization.  The  species 
is  named  in  honor  of  the  distinguished  botanist,  Professor 
Cassiano  Conzatti,  Director  of  the  Normal  School  in  the  City  of 
Oaxaca,  Mexico.

Field  Mus.).  The  affinity  of  C.  cinaloanum  is  in  all  probability 
with  the  obscure  C.  scabrum  Moc.  &  Sesse,  and  it  may  eventually 
prove  to  be  conspecific.  The  leaf-margins  on  an  individual 
plant  often  vary  from  entire  to  conspicuously  dentate  in  the 
apical  portion;  and  the  inflorescence,  here  as  in  several  other 
species  of  the  genus,  may  be  either  simple  or  compound. 

Citharexylum  Rosei  Greenman,  sp.  nov. 

Stem  and  branches  covered  with  a  grayish  or  reddish  brown 
cortex,  terete  or  subtetragonal ;  ultimate  branchlets  4-angled, 
cinereous-hirsute:  leaves  opposite,  lanceolate  or  oblanceolate, 

1  to  3  cm.  long,  1  cm.  or  less  broad,  obtuse  to  rounded  at  the 
apex,  entire,  narrowed  below  to  a  subpetiolate  base,  hirtellous- 
pubescent  on  the  upper  surface,  cinereous-tomentulose  beneath: 
inflorescence  terminating  the  branchlets  in  few-flowered  short 
racemes;  pedicels  3  to  4.5  mm.  long:  flowers  not  seen:  calyx 
persistent  and  in  the  fruiting  stage  2  to  2.5  mm.  high,  shallow, 
somewhat  saucer-shaped,  truncate,  pubescent:  mature  fruit 
oblong,  7  to  8  mm.  long  in  the  dried  state;  pyrenae  elliptic,  6  to 
7  mm.  long,  concavo-convex,  strongly  corrugated  on  the  outer

C.  Altamiranum  to  which  it  is  closely  related,  but  from  which 
it  differs  amply  in  having  smaller  leaves  of  different  outline,  a 
more  dense  tomentum,  and  in  its  shorter,  shallower  and  trun¬ 
cate  calyx,  and  corrugated  pyrenae. 

Vitex  Gaumeri  Greenman,  sp.  nov. 

Tree,  10  to  15  m.  in  height:  branches  covered  with  a  grayish

petiolate,  palmately  compound;  petioles  3  to  9.5  cm.  long,  vel¬ 
vety  pubescent;  leaflets  5  to  7,  petiolulate,  ovate  to  elliptic- 
oblong,  rarely  tending  to  become  obovate,  1.5  to  11  cm.  long, 
0.5  to  5.  cm.  broad,  usually  short-acuminate  and  acute  or  occa¬ 
sionally  rounded  at  the  apex,  entire,  obtuse  to  subcordate  at

and  densely  tomentulose  beneath ;  midrib  and  lateral  veins 
prominent  on  the  under  surface,  but  the  anastomosing  of  the 
ultimate  veins  not  conspicuously  reticulated;  petiolules  0.5  to 
2.7  cm.  in  length,  velvety  pubescent:  the  pedunculate  panicu¬ 
late  cymes  axillary,  clustered  at  the  ends  of  the  branches,  2  dm. 
or  less  in  length:  calyx  small,  2.5  mm.  long,  subbilabiate,  rather 
acutely  5-toothed,  externally  pubescent:  corolla  irregular, 
bilabiate,  about  9  mm.  long;  tube  erect,  5  mm.  high,  narrowly

The  species  here  described  is  nearly  related  to  V.  pyramidata 
Rob.  with  which  it  has  been  confused,  but  from  which  it  differs 
in  being  a  tree  instead  of  a  shrub,  in  having  longer  petiolules 
which,  as  well  as  the  petioles  themselves,  are  velvety  pubes¬ 
cent  instead  of  pulverulent,  in  having  a  paler  lower  leaf-surface, 
smaller  flowers,  in  the  absence  of  villous  hairs  at  the  base  of  the 
anterior  lip  of  the  corolla  on  its  upper  surface,  and  finally  in 
having  a  more  pubescent  and  somewhat  more  sharply  dentate 
calyx.  Dr.  George  F.  Gaumer  in  whose  honor  the  above  species 
is  named  states  that  the  plant  here  described  is  a  tree  growing 
in  the  forests  about  Izamal,  where  it  attains  a  height  of  about 
15  meters.  The  flowers,  moreover,  are  said  by  Dr.  Gaumer  to 
be  bright  purple.  The  tree  passes  under  the  native  Mayan 
name  of  “Yaxnic.”

This  species  has  been  referred  hitherto  to  M.  Royoc  L.,  but 
it  may  be  readily  separated  by  the  persistent  pubescence  over 
the  entire  plant,  the  sessile  or  subsessile  inflorescence  and  fruit 
slightly  shorter  corolla,  somewhat  more  complete  union  of  the 
flowers,  and  by  the  slightly  longer  and  more  oblique  pyrenae.

Professor  William  Trelease  has  kindly  furnished  me  with  a  copy 


264  Field  Columbian  Museum  —  Botany,  Vol.  II. 

of  the  original  descriptions  and  a  photograph  of  the  illustration 
of  the  above  species  from  the  Revue  Horticole. 

I  am  indebted,  moreover,  to  Dr.  Casimir  DeCandolle  who 
has  kindly  made  for  me  a  critical  comparison  of  my  no.  209  with 
Crusea  calocephala  DC.  in  the  Prodromus  herbarium.  From 
Dr.  DeCandolle’s  letter  I  quote  the  following: —  “I  have  com¬ 
pared  the  Crusea  specimens  you  sent  me  with  that  of  C.  caloce¬ 
phala  in  the  Prodromus  herbarium.  The  case  of  that  species 
is  unfortunately  not  quite  clear  as  you  will  see  by  the  following: 
C.  calocephala  DC.  is  represented  in  the  herbarium  by  Mocino’s 
plate  n.  497  (an  original  plate,  by  the  way,  and  not  a  tracing), 
together  with  Dunant’s  specimen  from  Peru.  Now  it  happens 
that  these  two  documents  do  not  seem  to  belong  to  the  same 
species,  for  the  plate  (of  which  I  sent  you  yesterday  a  good 
tracing,  in  a  separate  roller)  shows  penninerved  leaves,  whilst 
in  Dunant’s  specimen  the  leaves  have  the  same  nervation  as  in 
your  specimen.  Now  on  the  other  hand  Dunant’s  specimen 
differs  from  yours —  1st  by  the  shape  of  its  involucral  leaves 
which  are  more  attenuate  at  the  base;  2d  by  its  calyx  being 
densely  pubescent  from  its  base  upwards,  whilst  in  your  specimens 
it  is  much  less  pubescent  and  mostly  on  its  upper  part  only. 
Consequently  I  consider  your  specimens  as  specifically  distinct 
from  both  Mocino’s  plate  and  Dunant’s  specimen. 

Moreover  I  must  also  draw  your  attention  to  the  fact  that  in 
Mocino’s  plate,  the  corolla  is  coloured  in  red  (which  please 
inscribe  on  the  tracing  when  it  reaches  you)  whilst  your  plant 
seems  to  have  blue  flowers.  As  for  C.  rubra  Cham.  &  Schlecht. 
it  is  also  certainly  distinct  from  your  plant,  as  it  has  much 
shorter  and  strigose  hairs  and  longer  petioles.” 

Both  C.  calocephala  DC.  and  C.  rubra  Cham.  &  Schlecht.  are 
somewhat  confused,  and  very  little  is  known  about  C.  violacea 
Brongn.  In  fact  the  entire  genus  Crusea,  as  well  as  Spermacoce , 
needs  a  careful  revision,  which,  however,  can  only  be  done 
satisfactorily  after  a  critical  comparison  of  the  ample  material 
of  our  recent  collections  with  types  existing  only  in  European 
herbaria. 

Lobelia  regalis  Fernald,  Proc.  Am.  Acad,  xxxvi.  503  (1901). 

Excellent  specimens  of  this  species  were  collected  at  Ejutla, 
State  of  Oaxaca,  Mexico,  altitude  1,300  m.,  12  December,  1906, 
C.  Conzatti,  no.  1638  (hb.  Field  Mus.).  This  collection  records 
another  station  for  one  of  the  most  beautiful  species  of  the  genus, 
and  one  which  is  well  worthy  of  introducing  into  cultivation.

Brickellia  Kellermanii  Greenman,  sp.  nov. 

Stem  erect,  nearly  1  m.  in  height,  lignescent  at  the  base, 
terete,  tomentulose:  lower  leaves  opposite,  the  upper  alternate, 
short-petiolate,  oblong-lanceolate,  3  to  6  cm.  long,  1  to  2  cm. 
broad,  obtuse  or  acute,  crenate-dentate  to  entire,  subhirtellous 
above,  paler  and  whitish-tomentulose  beneath,  rather  strongly 
reticulate-nerved ;  petioles  about  0.5  cm.  long:  inflorescence 
a  subcorymbose  rather  leafy  panicle :  heads  many,  sessile  or  nearly 
so,  12  to  14  mm.  high,  usually  12-flowered:  involucre  narrowly 
campanulate  or  subcylindric ;  bracts  of  the  involucre  about  7- 
seriate,  strongly  unequal,  imbricated,  sparingly  pubescent, 
ciliate,  striate,  pale  with  greenish  nerves,  or  purplish;  the  outer 
bracts  ovate-oblong,  mucronate,  strongly  ciliate,  the  inner 
lance-linear,  acute:  flowers  somewhat  exceeding  the  involucre: 
pappus  silvery  white,  6  mm.  long,  about  as  long  as  the  white  or 
purplish-tinged  corolla:  achenes  3  mm.  long,  pubescent. —

Minas,  altitude  1,11:8  m.,  3  March,  1007,  W.  A.  Keller  man,  no. 
6127  (hb.  Field  Mus.). 

In  leaf-outline  B.  Kellermanii  resembles  B.  cylindrica  and  B. 
Pringlei  Gray,  but  it  is  amply  distinct  from  both  these  species  in 
the  nature  of  the  inflorescence,  tomentum,  and  in  the  technical 
characters  of  the  head.

Sp.  PI.  892  (1753);  Willd.  Sp.  PI.  iii.  2167  (1800). 

This  species  was  based  on  material  collected  by  Houston  in 
the  region  of  Vera  Cruz,  Mexico.  Specimens  obtained  at  La 
Purga,  31  kilometers  southwest  of  the  City  of  Vera  Cruz,  27 
January,  1906,  J.  M.  Greenman ,  no.  257  (hb.  Field  Mus.),  agree 
well  with  the  early  although  brief  descriptions  of  the  above 
species,  and  are  confidently  referred  to  it.  The  species  is  of 
rather  wide  distribution,  occurring  in  southern  Mexico,  the 
West  Indies  and,  according  to  Hemsley,  in  South  America; 
it  is,  moreover,  well  characterized  by  its  viscid-hirsute  character 
and  somewhat  lyrate  or  pinnately  incised  foliage,  suggesting 
vigorous  forms  of  Senecio  viscosus  L. 

In  1890  and  again  in  1892  Mr.  C.  G.  Pringle  collected  on  river 
banks  at  Las  Palmas,  Mexico,  an  Egletes  which  was  referred  to  E. 
viscosa  Less.  The  latter  of  the  two  collections  made  by  Mr. 
Pringle  was  distributed  by  clerical  error  as  11  Egletes  viscida 
Less.”  Mr.  Pringle’s  specimens  differ  in  several  particulars 
from  Lessing’s  species.  Moreover,  they  do  not  correspond  to 
any  known  species  of  the  genus,  hence  they  may  be  characterized 
as  follows: 

Egletes  Pringlei  Greenman,  sp.  nov. 

Annual:  stem  erect  or  essentially  so,  simple  or  branched 
from  near  the  base,  somewhat  geniculate  above,  viscid-hirsute: 
leaves  ovate  to  more  or  less  obovate,  1.5  to  7.5  cm.  long,  one- 
half  to  two-thirds  as  broad,  thin  or  membranous,  rather  coarsely 


266  Field  Columbian  Museum  —  Botany,  Vol.  II. 

and  unequally  sinuate-dentate,  contracted  below  into  a  narrowly 
winged  petiole  and  subamplexicaul  by  a  slightly  auricular  base: 
inflorescence  terminating  the  stem  and  branches  in  a  paniculate 
cyme:  heads  4  to  5  mm.  high,  radiate:  ray-flowers  many- 
seriate;  corollas  minute,  1.5  to  2  mm.  long,  less  than  0.5  mm. 
broad:  disk-flowers  numerous;  corollas  about  1  mm.  long, 
4-5-toothed;  tube  on  the  outer  surface  glandular-pilose:  achenes 
slightly  compressed,  produced  above  into  a  somewhat  irregular 
saucer-shaped  subcartilaginous  pappus. —  Mexico.  State  of 
San  Luis  Potosi:  river  banks,  Las  Palmas,  4  June,  1890,  C.  G.

June,  1892,  C.  G.  Pringle,  no.  4101  (hb.  Field  Mus.). 

E.  Pringlei  is  readily  distinguished  from  E.  viscosa  Less,  by 
the  ovate  or  obovate  undivided  leaves,  the  more  numerous 
heads,  shorter  hairs  on  stem  and  branches,  and  finally  by  the 
smaller  narrower  rays,  the  more  conspicuously  flaring  pappus, 
and  the  less  conical  receptacle. 

Erigeron  pacayensis  Greenman,  sp.  nov. 

Suffruticose :  stems  erect  or  ascending,  branched,  1  to  1.5 
dm.  high,  pubescent  with  upwardly  appressed  or  but  slightly 
spreading  hairs:  leaves  narrowly  linear-oblanceolate,  1  to  2 
cm.  long,  1  to  3  mm.  broad,  acute  or  obtusish,  entire  or  bearing 
a  single  tooth  on  one  or  both  margins,  gradually  narrowed  below 
to  a  subpetiolate  base,  sparingly  pubescent  on  either  surface  to 
nearly  glabrous:  heads  few,  small,  5  to  6  mm.  high,  less  than 

1  cm.  in  diameter  including  the  rays,  terminating  the  stem 
and  branches  on  long  slender  appressed-pubescent  peduncles 
6  cm.  or  less  in  length:  involucre  subcampanulate;  bracts  of 
the  involucre  about  3 -seriate,  unequal,  lance-linear,  acute, 
appressed-pubescent,  more  or  less  purplish;  the  outer  bracts 
shorter:  ray-flowers  3-seriate,  many;  rays  narrow,  white  or 
roseate:  flowers  of  the  disk  numerous:  pappus  bristles  slender, 

2  to  2.5  mm.  long:  achenes  pubescent. —  Guatemala.  Depart¬ 
ment  of  Amatitlan:  crater  of  the  Volcano  of  Pacaya,  altitude 
2,500  m.,  6  January,  1907,  W.  A.  Kellerman,  no.  61 11  (hb.  Field 
Mus.,  and  hb.  Gray). 

The  species  here  proposed  has  its  affinity  with  Erigeron  Ervend- 
bergii  Gray,  and  *E.  irazuensis  Greenman.  From  the  former 
it  differs  in  having  smaller  heads,  appressed  instead  of  spreading 
hairs  on  the  involucre,  more  unequal  involucral  bracts,  etc. 
Although  similar  in  habit  to  E.  irazuensis,  yet  it  differs  in  several 
particulars,  namely  in  having  narrower  and  less  pubescent 
leaves,  also  in  the  appressed  pubescence  on  the  stem  and  pedun¬ 
cles,  as  well  as  in  other  details. 

I  am  indebted  to  Mr.  H.  H.  Bartlett  of  the  Gray  Herbarium 
for  a  critical  comparison  of  Professor  Kellerman’s  plant  with  the 
type  of  E.  irazuensis.

Baccharis  Kellermanii  Greenman,  sp.  nov. 

Stem  terete,  sulcate,  hirtellous-puberulent  with  crisp  sordid 
hairs:  leaves  elliptic-lanceolate  to  oblanceolate,  1  to  3.5  cm. 
long,  2  to  8  mm.  broad,  acute  or  obtuse,  sharply  dentate  with 
unequal  and  somewhat  spreading  teeth,  narrowed  at  the  base 
into  a  short  petiole,  at  first  slightly  puberulent  above  but  soon 
becoming  glabrous,  persistently  hirtellous-pubescent  beneath, 
subtrinervate  and  rather  prominently  reticulate- veined :  in¬ 
florescence  a  terminal  subcorymbose  cyme:  heads  of  the  pistil¬ 
late  plant  numerous,  6  to  7  mm.  high:  involucre  subcampanu- 
late;  bracts  of  the  involucre  unequal,  4-5-seriate,  linear-ob-long, 
obtuse  or  rounded  at  the  tip,  more  or  less  purplish  on  the 
back  and  ciliate  towards  the  apex,  the  outermost  shortest: 
flowers  18  to  24;  pappus  about  4  mm.  long,  slightly  tawny, 
exceeding  the  slender  corolla-tube:  mature  achenes  1.5  mm. 
long,  glabrous:  staminate  plant  not  seen. —  Guatemala.  De¬ 
partment  of  Solala:  Volcano  of  Atitlan,  16  February,  1906,

Baccharis  Kellermanii  suggests  B.  thesioides  HBK.,  but  the 
two  species  are  amply  distinct  in  habit,  inflorescence,  involucral 
details,  and  in  the  character  of  the  surface  of  stem  and  leaves. 

Gnaphalium  brachyphyllum  Greenman,  sp.  nov. 

An  herbaceous  perennial,  lanate-tomentose  throughout:  stems 
several,  erect  or  nearly  so,  from  a  ligneous  base,  1  to  2  dm.  high, 
slender,  leafy:  leaves  linear-oblong  or  slightly  oblanceolate, 
0.5  to  1.5  cm.  long,  1  to  4  mm.  broad,  obtuse,  entire,  slightly 
repand-margined,  sessile  and  semiamplexicaul,  densely  lanate- 
tomentose  on  both  surfaces :  inflorescence  terminating  the  stems 
in  rather  dense  cymes:  heads  4  to  5  mm.  high:  involucre  sub-

glabrous;  bracts  of  the  involucre  3-4-seriate,  pale  stramineous, 
the  outer  ovate  and  about  3  mm.  long,  the  inner  linear-lanceolate, 
3.5  to  4  mm.  long,  greenish  at  the  base  especially  along  the 
median  line:  pistillate  flowers  numerous:  perfect  flowers  6  to  10: 
pappus  caducous:  achenes  glabrous,  1  mm.  long,  reddish. — •

Vienna  in  1905,  it  becomes  necessary  to  form  the  above  binomial 
for  this  well  known  south  Mexican  and  Central  American  species. 

Wedelia  rugosa  Greenman,  sp.  nov. 

An  herbaceous  perennial:  stems  erect  or  nearly  so,  5  dm.  or 
more  high,  simple  or  branched,  subterete,  strigose-hispid  with 
upwardly  appressed  hairs:  leaves  opposite,  short-petiolate, 
oblong  to  oblong-lanceolate,  3  to  10  cm.  long,  1.5  to  5  cm.  broad, 
acute  or  obtuse,  entire  or  slightly  crenate-dentate,  rounded  to 
subcordate  at  the  base,  tuberculate-hispid  and  rugose  above, 
hirsute-hispid  and  strongly  reticulate-nerved  beneath;  petioles 
2  to  5  mm.  long:  inflorescence  terminating  the  stem  and  branches 
in  few-headed  cymes:  heads  radiate,  5  to  8  mm.  high,  including 
the  rays  10  to  16  mm.  in  diameter;  peduncles  0.5  to  4  cm.  long, 
strigose-hispid:  involucre  campanulate;  bracts  of  the  involucre 
biseriate,  oblong  to  elliptic-ovate,  3  to  4  mm.  long,  1  to  1.5  mm. 
broad,  obtuse  or  acute,  externally  appressed-pubescent :  ray- 
flowers  12  to  14,  fertile;  rays  yellow,  about  6  mm.  long,  2.5  mm. 
broad,  2-3-dentate;  achenes  3-angled:  disk-flowers  numerous; 
achenes  at  first  laterally  compressed,  densely  atomiferous- 
glandular  over  the  upper  one-third,  glabrous  below,  at  maturity 
oblong,  2.5  mm.  long  and  subquadrangular  in  cross-section: 
pappus  of  both  ray-  and  disk-flowers  a  fimbriate  crown  of  2  (-3) 
small  scales  at  the  angles  of  the  achene  with  minute  more  or 
less  coalescent  intermediate  scales :  pales  of  the  receptacle  rather 
conspicuous,  more  or  less  uncinate-tipped  especially  in  the 
mature  state. —  Wedelia  reticulata  Greenm.  in  Trans.  Acad.

Var.  tenuis  Greenman,  var.  nov. 

Similar  to  the  species,  but  with  smaller  and  more  slender  stems : 
leaves  2.5  to  6  cm.  long,  0.5  to  2.2  cm.  broad. —  Cuba.  Province 
of  Pinar  del  Rio:  Herradura,  30  September,  1904,  Carl  F.

H.  A.  Van  Hermann,  no.  705  (hb.  Field  Mus.). 

The  species  here  described  resembles  W.  reticulata  DC. ;  but 
the  oblong  or  oblong-lanceolate  outline  of  the  leaves  with  their 
distinctly  pinnate  venation  and  entire  or  slightly  crenate  margin, 
the  shorter  involucral  bracts,  and  the  peculiar  uncinate-tipped 
pales  amply  distinguish  it  from  the  De  Candolle  species. 

Perymenium  Goldmanii  Greenman,  sp.  nov. 

Stem  terete  or  slightly  tetragonal,  striate,  strigillose:  leaves 
opposite,  petiolate,  ovate-lanceolate,  3  to  8  cm.  long,  1  to  4  cm. 
broad,  acuminate,  acute,  dentate  to  subentire,  rounded  to  sub- 
cordate  at  the  base,  scabrous  above  and  becoming  slightly 
rugose  in  age,  hirsutish-pubescent  beneath,  green  on  both  sides, 
3 -nerved  from  near  the  base;  petioles  3  to  10  mm.  long;  inflores¬ 
cence  terminating  the  stem  and  the  horizontally  spreading  or 
ascending  lateral  branches  in  rather  dense  cymose  clusters: 
heads  numerous,  small,  6  to  7  mm.  high,  about  3  mm.  in  diameter, 
radiate;  primary  and  secondary  peduncles  short,  usually  less 
than  2  cm.  in  length,  appressed-pubescent ;  involucre  subcampan- 
ulate;  bracts  of  the  involucre  unequal,  2-3-seriate,  the  outer 
shorter,  ovate  to  ovate-oblong,  3  to  4.5  mm.  long,  acute  or  ob¬ 
tuse,  externally  strigillose,  ciliate:  ray-flowers  commonly  5; 
rays  lemon-yellow:  disk-flowers  about  20:  pappus  of  numer¬ 
ous  unequal  setae:  mature  achenes  laterally  compressed  or 
somewhat  3-angled,  about  2.5  mm.  long,  ciliate  or  narrowly 
winged,  transversely  rugose  under  a  lens  and  slightly  pubes¬ 
cent  on  the  surface  especially  in  the  upper  half. —  Mexico. 
State  of  Campeche:  Apazote,  near  Yohaltun,  27  to  29  December, 
1900,  E.  A.  Goldman,  nos.  487,  502  (hb.  U.  S.  Nat.  Mus.,  and 
hb.  Field  Mus.). 

The  affinity  of  the  species  here  described  is  with  P.  micro- 
cephalum  Schz.  Bip.,  and  P.  gracile  Hemsl.,  but  it  differs  from 
the  former  by  the  larger  leaves  and  from  the  latter  in  foliar  and 
achenial  characters.  The  narrowly  winged  achenes  of  P.  Gold¬ 
manii  suggest  P.  gymnolomoides  DC.,  but  that  species  has  smaller 
leaves,  shorter  petioles  and  fewer  heads  in  the  inflorescence.

and  the  habit  of  the  plant  render  it  a  congener  of  Professor 
Urban’s  recently  published  genus  Notoptera,  Symb.  Antil.  ii.

A  careful  examination  of  a  considerable  number  of  specimens 
representing  this  species  shows  a  marked  variation  in  the  form 
and  size  of  the  outer  spreading  subfoliaceous  involucral  bracts. 
These  vary  from  spatulate  to  lanceolate  or  linear  and  from 
3  to  12  mm.  in  length.  There  is  also  some  diversity  in  the  size 
of  the  rays.  The  following  specimens  are  here  referred. — •

G.  sarmentosa  Greenman,  sp.  nov. 

Stem  prostrate  or  ascending,  rooting  at  the  lower  nodes,  terete, 
glabrous  below,  slightly  pubescent  above:  leaves  sessile,  or  the 
lowermost  short-petiolate,  ovate,  3  to  6  cm.  long,  two-thirds  as 
broad,  acute  or  mucronate-acute,  somewhat  oblique  or  unsym- 
metrical  at  the  base,  at  first  pubescent  with  a  few  scattered  hairs 
on  both  surfaces,  soon  glabrate:  inflorescence  terminating  the 
stem  and  branches  in  few-headed  cymes:  heads  pedunculate, 
including  the  rays  about  1.5  cm.  in  diameter;  peduncles  slender, 
1  to  7  cm.  long,  naked  or  sparingly  bracteolate,  subappressed- 
pubescent:  involucre  6  to  8  mm.  high;  bracts  glabrous,  yellow¬

involucre  suggests  some  of  the  Galinsogece,  particularly  Calea  and 
Geissolepis,  and  certain  of  the  Helenioideoe,  especially  Jaumea.

This  species  has  its  affinity  with  a  small  natural  group  of 
plants  to  which  B.  rubifolia  HBK,  B.  tereticaulis  and  B.  coreopsidis 
DC.  belong,  but  the  smooth  or  lineate-puberulent  stem  and 
branches,  the  pinnatisect  leaves  with  their  numerous  narrow 
divisions,  the  nature  of  the  pubescence,  and  certain  technical 
characters  of  the  head  seem  to  the  writer  to  warrant  its  specific 
rank.  B.  Urbanii  is  apparently  most  closely  allied  to  B.  Coreop¬ 
sidis,  var.  (?)  incisa  DC.  v.  599  (1836)  ( Coreopsis  incisa  Ker- 
Gawl.  Bot.  Reg.  t.  7),  but  here  again  a  careful  comparison  with 
the  original  description  and  illustration  shows  several  important 
differences. 

Calea  Pringlei  Rob.,  var.  rubida  Greenman,  var.  nov. 

Leaves  short-petiolate,  ovate,  1.5  to  3  cm.  long,  two-thirds 
as  broad,  densely  tomentose  beneath;  petioles  2  to  4  mm. 
long,  tawny-pubescent:  involucral  bracts  elliptic-oblong,  red- 
dish-margined. —  Mexico.  State  of  Vera  Cruz:  on  hillsides

short  but  distinctly  petioled  leaves,  and  by  the  slightly  narrower 
and  reddish-margined  involucral  bracts. 

Florestina  Liebmannii  Schz.  Bip.,  in  herb. 

Stem  erect  or  somewhat  ascending  from  an  indurated  base,  3 
to  5  dm.  high,  simple  or  sparingly  branched,  terete  below, 
striate-angled  above,  substrigillose  and  more  or  less  closely 
beset  with  stipitate  glands:  lower  leaves  opposite,  simple, 
petiolate,  narrowly  lanceolate-oblong,  2  to  3.5  cm.  long,  4  to 
12  mm.  broad,  obtuse  or  acute,  entire  or  occasionally  few-dentate, 
obtuse  at  the  base,  substrigose-hispid  on  both  surfaces,  3-nerved; 
petioles  0.5  to  1.5  cm.  long,  hispid-pubescent  intermixed  with 
stipitate-glandular  hairs;  the  upper  stem-leaves  alternate  and 
gradually  reduced  to  linear  bracts:  inflorescence  terminating 
the  stem  in  a  glandular-pubescent  subcorymbose  cyme:  heads 
homogamous,  8  to  10  mm.  high:  involucre  sub  turbinate ;  bracts  of 
the  involucre  8,  uniseriate  or  essentially  so,  elliptic-oblong  to 
obovate-oblong,  4  to  5  mm.  long,  2  to  3  mm.  broad,  rounded  at 
the  apex,  scarious-margined  and  more  or  less  erose-ciliate,  ap-

The  general  habit  and  simple  leaves  of  this  species  suggest 
a  relationship  with  Palafoxia  or  Polypteris,  but  the  technical 
characters  of  the  involucre,  pappus,  corolla  and  style-branches 
place  it  rather  with  Florestina.  The  affinity  of  the  plant,  as 
well  as  its  specific  rank,  was  first  recognized  by  Schultz  Bipontinus, 
and  subsequently  by  the  late  Professor  F.  W.  Klatt,  but  the 
name  seems  not  to  have  been  hitherto  published. 

I  am  indebted  to  Professor  Eug.  Warming  for  the  identifica¬ 
tion  of  my  no.  114  with  the  Liebmann  plant  in  the  Botanical 
Museum  at  Copenhagen. 

Tagetes  jaliscensis  Greenm.,  var  minor  Greenman,  var.  nov. 

Leaves  3  cm.  or  less  in  length,  about  two-thirds  as  broad : 
heads  1.3  to  1.8  cm.  high;  involucre  1  to  1.4  cm.  long:  mature 
achenes  7  to  7.5  mm.  in  length. —  Mexico.  State  of  Oaxaca: 
Cercainas  de  Oaxaca,  altitude  1550  m.,  8  November,  1906,  C.

characters  separating  var.  minor  from  the  species  are  the  smaller 
leaves,  shorter  involucre  and  flowers. 

Dysodia  (§Gymnolaena)  oaxacana  Greenman,  sp.  nov. 

Shrub:  stem  and  branches  covered  with  a  grayish  bark;  ulti¬ 
mate  branchlets  terete,  somewhat  striate,  greenish  or  reddish- 
brown,  minutely  pubescent  in  decussating  lines:  leaves  opposite, 
sessile  or  essentially  so,  lanceolate,  1  to  4  cm.  long,  4  to  11  mm. 
broad,  acute,  finely  serrulate,  narrowed  below  to  an  entire  or 
occasional  subsetiferous  subpetiolate  base,  pellucid-punctate, 
slightly  pubescent  on  both  surfaces  under  a  lens  especially  on 
the  midrib  of  the  upper  surface,  or  glabrous:  heads  few,  hetero- 
gamous,  1.5  to  2  cm.  high,  terminating  the  stem  and  branches 
on  minutely  bracteate  1.5-5  cm. -long  glabrous  peduncles:  involu¬ 
cre  at  first  narrowly  campanulate  or  subcylindric,  often  split  on 
one  side,  12  to  14  mm.  long,  (7-)  8-dentate,  naked  or  essentially 
so  at  the  base,  glabrous,  bearing  several  linear-elliptic  glands, 
later  separating  into  more  or  less  distinct  lance-linear  bracts; 
teeth,  or  the  terminal  portion  of  the  individual  bracts,  short, 
triangular,  acute,  pubescent-tipped:  ray-flowers  commonly  8;

instead  of  a  multiflorous  corymb,  and  pubescent-tipped  invo- 
lucral  bracts. 

To  this  natural  group  also  belong  D.  integrifolia  Gray,  and 
D.  Seleri  Rob.  &  Greenm.  From  the  former  the  species  described 
above  is  readily  separated  by  the  pubescent  branchlets  and 
puberulent  leaves ;  and  from  the  latter  by  the  presence  of  pellucid 
glands  on  leaves  and  involucre.

ovate-oblong  in  general  outline,  2  to  3  dm.  long,  1.5  to  2  dm. 
broad,  pinnately  lobed  with  deep  narrow  sinuses,  abruptly  or 
somewhat  gradually  contracted  at  the  base  into  the  petiole, 
reticulately  veined  above  and  sparingly  puberulent  over  the

Senecio  (§  Terminales)  serraquitchensis  Greenm. 

Suffruticose :  stem  above  tawny-tomentose:  leaves  petiolate, 
oblong-lanceolate  to  somewhat  oblong-obovate,  1.2  to  2.5  dm. 
long,  3  to  9  cm.  broad,  mucronate-acute,  slightly  sinuate,  remotely 
cartilaginous-denticulate,  narrowed  below  to  the  tomentulose 
2.5  to  6.5  cm. -long  petiole,  at  first  tomentulose  on  both  surfaces 
especially  on  the  midrib  and  lateral  nerves  beneath,  but  soon 
glabrate  and  rather  strongly  reticulate-veined :  inflorescence 
abruptly  terminating  the  stem  in  one  or  more  long-pedunculate 
compound  many-headed  corymbs:  heads  about  1  cm.  high, 
radiate:  involucre  barely  calyculate  with  minute  bracteoles; 
bracts  of  the  involucre  8,  narrowly  oblong,  about  4  mm.  long, 
obtuse,  turning  blackish  in  drying:  ray-flowers  5;  ligules  short, 
4-nerved;  tube  shorter  than  the  pappus:  disk-flowers  5  or  6;

foliage,  longer  and  fewer  (5  instead  of  8)  involucral  bracts.

26  December,  1906,  no.  1,646  (hb.  Field  Mus.)  agree  well  with 
specimens  secured  by  Mr.  Pringle  on  which  the  species  was 
based,  except  the  leaves  in  the  Conzatti  plant  have  a  maximum 
breadth  of  2.5  centimeters.
